# The sed goo here:
# 1. unescapes new lines and smashes them into a single non-delimiting character
# 2. unescapes anything else (mainly quote marks)
# 3. strips off the s "..." around the result
# 4. smashes </interface> into a single character, so we can do a non-greedy
# match for it.
# 5. smashes the interface into a single character, so we can do a non-greedy
# match for it
# 6. do the aforementioned matches to erase all interfaces from output we
# weren't asked for
# 7. restore </interface> and the interface to their true selves
# 8. likewise, put the new lines back in the stream
